A total of 90 reputable firms in the construction industry were randomly selected for interview to obtain expert views on 24 selected factors. The target group was Architects, Quantity Surveyors, Project Managers, Engineers, and Construction Managers. 90 structured questionnaires were administered. The null hypothesis was tested using Bartlett's test of sphericity on the data and the results showed a 99.9% level of significance, thus, the null hypotheses were rejected.
